A method of retrieving security information in a media access control (MAC) header by a wireless station may include receiving a data unit, such as a protocol data unit (PDU), from a remote wireless station. The PDU may include the MAC header. The method may also include reading two encryption key sequence (EKS) bits in the MAC header that denote both whether the data unit is encrypted and a position in an encryption key sequence for the data unit.

Optimizing security bits in a media access control (MAC) header

A method and apparatus to control interaction between two multi-threaded processor engines is presented. A first multi-threaded processor engine is configured for connection to a serial link, and performs receive and transmit operations in a first 'PHY' mode of operation. A second multi-threaded processor engine is operable to process data received by the first multi-threaded processor over the serial link and to provide the processed data to the first multi-threaded processor engine for transmission over the serial link, when the first multi-threaded processor operates in the PHY mode. Additionally, the first multi-threaded processor engine is configured to execute certain operations, e.g., hardware accelerator operations, at the request of the second multi-threaded processor engine in a second 'co-processor' mode of operation.
